IMPROVEMENT IN REGULATORS FOR EXHAUSTERS IN GAS-WORKS.

Specification forming part of Letters Patent No. 119,505, dated October3, 1871.

To all whom it may concern:

Be it known that I, ADAM S. CAMERON, of the city, county, and State ofNew York, have invented a new and Improved Regulator for Exhausters inGasWorks; and I do hereby declare the following to be a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanying drawingforming part of this specification, in which drawing Figure 1 representsa longitudinal vertical section of this invention. Fig. 2 is a plan ortop view of the same.

Similar letters indicate corresponding parts.

This invention consists in a vessel hung on gudgeons so that it canfreely oscillate, and provided with a partition which extends nearlydown to the bottom of said vessel and divides the same in twocompartments, one of which is closed on top while the other is open, incombination with a pipe which communicates with the exhaust-pipe of thegas-works, and which opens into the closed compartment of theoscillating vessel, said oscillating vessel being connected with thethrottle-valve of the steam-engine, which imparts motion to theexhauster in such a manner that when the oscillating vessel is partiallyfilled with water and the force of the exhauster exceeds the desiredlimit the water will rise in the closed chamber, thereby causing thischamber to sink down, and closing the throttle-valve of the engine; andas soon as the force of the exhaust is reduced the water returns fromthe closed to the open chamber, the throttle-valve is again opened, andthe engine reassumes its original force. An adjustable weight secured toone side of the vessel serves to regulate the oscillating motion of thevessel and to adapt it to the desired force of the exhauster.

In the drawing, A designates a vessel, which is hung on gudgeons a, (bypreference knife-edge bearings,) so that it can oscillate with the leastpossible friction. Said vessel is divided in two compartments orchambers, b c, by a vertical partition, d, which is open at its bottomedge, so that water or other liquid poured into the vessel can freelypass from one chamber to the other. The gudgeons of the vessel A havetheir bearings on standards B, which rise from a suitable bed-plate, (J;and from one of these standards extends a bracket, e, which forms thesupport for apipe, D. This pipe connects with the hydraulic main or withthe exhaust-pipe of the gas-works, and it extends down through the opentop of the chamber I), through under the partition 01, and up into thechamber 0, which is firmly closed at its top, as shown in Fig. .l of thedrawing. From one edge of the vessel A extends a rod, F, which connectswith the throttle-valve of the exhaustingengine. The oscillating motionof the vessel A is confined within certain limits by stops f f, whichare cast or otherwise secured to the bottom or side of the vessel, andwhich, when the oscillating motion reaches the desired limit, strikeagainst one of the standards B, or against a projection, 9, extendingfrom one of said standards. On the top of the vessel A is placed aweight, E, which slides on a rib, h, and which is held in position by aset-screw, 4;. By moving this weight in or out the motion of the vesselA can be regulated.

When the vessel A is filled with water or other liquid and theexhaustingengine is started the air or gas on the top of the liquid inthe closed chamber 0 israrefied and the liquid in this chamber rises.WVhile itdescends in the open chamber b the equilibrium of the vessel Ais disturbed and the throttle-valve of the engine is closed. Byadjusting the weight E the time when the throttlevalve closes can beadapted to a greater or less rarefaction of the air in the closedchamber 0. When the speed of the engine is reduced the water sinks downin the closed chamber, the vessel A returns to its original position,and the throttle-valve is again opened.

By these means the action of the exhauster in gas-works is renderedself-regulating, and an apparatus is obtained which is very simple inits construction, and which in its operation requires but littleattention.

What I claim as new, and desire to secure by Letters Patent, is

1. The oscillating vessel A, with its partition d, in combination with apipe, D, connecting with the hydraulic main or exhaust-pipe ofgas-works, substantially as described.

2. The adjustable weight E, in combination with the oscillating vessel Aand pipe D, substantially as set forth.

This specification signed by me this 20th day of July, 1871.
